TL;DR: In this paper, nearly 2000 herbarium specimens and 232 species of the genera Homalium and Hybanthus were analysed for nickel in order to identify plant accumulators of nickel which were indicative of nickeliferous (usually ultrabasic) rocks.

TL;DR: In this article, a review of the current status of technology deployment and recommendations for future remediation research is presented. And the authors also elucidate and compare the available technologies that are currently being applied for remediation of heavy metal(loid) contaminated soils, as well as the economic aspect of soil remediation for different techniques.

TL;DR: In this paper, a log-log plots for element concentration-area and perimeter-area relations were employed to separate geochemically anomalous areas from background, where the values used for perimeters and areas are the lengths and enclosed areas of geochemical isopleths obtained by interpolation.

TL;DR: Kerogen is defined as the portion of organic matter in sedimentary rocks that is insoluble in organic solvents and is formed from formerly living organic materials by diagenetic processes in the first few hundred meters of burial and is partially converted, under the influence of temperature and time, into petroleum by a series of complex, first-order reactions, termed catagenesis as discussed by the authors.

TL;DR: In this article, a method of choosing threshold values between anomalous and background geochemical data, based on partitioning a cumulative probability plot of the data is described, which is somewhat arbitrary but provides a fundamental grouping of data values.
